Abstract
Background
In a world where travelling can play a central role among human activities, due to the migratory flows increase and to the facilitation of exchanges between distant countries, the need to ensure healthcare to all travellers becomes a key point among healthcare activities. The aim of the study is to assess Italian Travel Clinics activity, critical issues, requirements and tips for improvement.
Methods
During the period from May to September, the Italian Society of Travel Medicine and Migrations (SIMVIM), performed a national on-line survey addressed to all Italian Travel Clinics.
Results
More than a third of Italian Travel Clinics replied the survey (79 clinics). The results show that on average for each clinic there are 4 healthcare workers (2 physicians, 1 nurse and 1 health worker), about 10 hours/week are dedicated to the clinic, the users are 18 and the Visiting Friends and Relatives (VFR) are 17%. In only 25% of cases the clinic is open access and in 80% there is a digital immunization registry. More than 70% of the healthcare workers have the last update in the two-year period of 2017/2018. Major critical issues are shortage of staff, limited opportunities to update, absence of a dedicated software, expensive vaccinations particularly for VFR, reduced visibility of the clinic and difficulties in accessing, Travel Clinics not sufficiently integrated into the National Health System.
Conclusions
Italian Travel Clinics are carring out a good service to ensure healthcare to the greatest number of travellers, but there is extensive room of improvement.
Key messages
We should create a network where Travel Clinics work together with General Practitioners, Pediatricians, other Specialists, Pharmacists, travel agents and above all with stakeholders. In this way Travel Clinics can involve an increasing number of travellers through an active offer of vaccinations and a careful risk assessment based on professional skills and expert knowledge.

Abstract
Prevalence of scapular dyskinesis varies across records, with overhead athletes being more frequently affected than non-overhead athletes A number of methods have been described to evaluate scapular kinematics and scapular dyskinesis. The "yes/no" and the "4-type" classification systems are widely accepted and diffusely used among orthopaedics and physical therapists. The inter-rater reliability for both the "yes/no" and the "4-type" classification systems may be different. Moreover, differences between physical therapists and orthopaedic surgeons may exist. Seven examiners (2 orthopaedic surgeons and 5 physical therapists) were asked to evaluate a mixed sequence of video recordings of healthy subjects and patients affected by shoulder, scapular or clavicular disorders and to assess scapular dyskinesis using the "yes/no" and the "4-type" classification systems. Cohen's kappa coefficient (κ) and weighted kappa were used to measure inter-rater reliability. Twenty-four subjects were enrolled. In general, the "4- type" system has higher κ values than ''yes/no'' classification system and orthopaedic surgeons achieve higher reliability than physical therapists for both systems. The clinical evaluation of active shoulder movements permits reproducible assessment and classification of scapular dyskinesis, in particular for the "4-type" classification system. The "4-type" classification system can be used to assess and classify scapular dyskinesis, especially among orthopaedic surgeons.

Abstract
PURPOSE To describe patterns of utilization, survival and infectious events in patients treated with rituximab at the University Hospital of Siena (UHS) to explore the feasibility of combining routinely collected administrative and hospital-pharmacy data for examining the real-world use of intravenous antineoplastic drugs. METHODS A retrospective, longitudinal cohort study was conducted using data from the Hospital Pharmacy of Siena (HPS) and the Regional Administrative Database of Tuscany (RAD). Patients aged ≥18 years with ≥1 rituximab administration recorded between January 2012 and June 2016 were identified in the HPS database. Anonymized patient-level data were linked to RAD. Rituximab utilization during the first year of treatment was described using HPS. Hospital diagnoses of adverse infectious events that occurred during the first year of follow-up and four-year survival were observed using RAD. RESULTS A total of 311 new users of rituximab were identified: 264 patients received rituximab for non-Hodgkin's lymphoma (NHL) and 47 were treated for chronic lymphocytic leukemia (CLL). Among new users with one complete year of follow-up (n = 203) over 95% received rituximab as the first-line treatment, and approximately 70% of them received 5-8 doses. No patient in the CLL group received >8 administrations. Four-year survival was approximately 70% in both CLL and NHL patients. Sepsis was the most frequent infectious event observed (5.1%). CONCLUSION HPS and RAD provided complementary information on rituximab utilization, demonstrating their potential for future pharmacoepidemiological studies on antineoplastic medications administered in the Italian hospital setting. Overall, this general description of the real-world utilization of rituximab in patients treated for NHL and CLL at UHS was in line with treatment guidelines and current knowledge on the rituximab safety profile.

Abstract
BACKGROUND The European Food Safety Authority (EFSA) has identified some risk factors for the occurrence of side effects linked to energy drinks (EDs) consumption by young people. EDs consumption has been evaluated in a sample of students in Italy together with some aspects of their lifestyle. METHODS The survey was performed in two high schools from September 2016 to June 2017. 583 students between 14 to 18 years were recruited and a standard questionnaire (EFSA checklist) was used to collect information on responders characteristics, beverages consumption, EDs with alcohol, and EDs and sports. RESULTS Despite 350 out of 583 responders (60%) consumed EDs, only 146 out of 583 (25%) were EDs-alcohol consumers. Moreover, 208 out of 379 (55%) of all physically active adolescents reported frequent EDs consumption before sport trainings. CONCLUSIONS Study results highlight the need for primary prevention measures in communication campaigns and training delivered by school to limit potential health threats related to excess of EDs consumption.

Abstract
A study was performed based on the design of a new wastewater treatment plant (WWTP) to be built in Weesp, The Netherlands (about 46,000 Population Equivalents (PE)). The conventional activated sludge plant was considered among the alternatives, with and without primary sedimentation. This pre-treatment technique is considered a sustainability measure as it improves the energy balance of the WWTP. However, at the same time, the question arose about the cost effectiveness of this measure. The scope of the study was to assess whether other sustainability measures (like solar panels) can realise the same level of sustainability with lower costs. The outcome of the study indeed shows that, for a new WWTP, it is considerably cheaper to avoid primary sedimentation and focus on other measures like solar panels instead. This appeared not only to be the case for the scale of WWTP Weesp, but also for WWTPs with capacities higher than 500,000 PE. For existing WWTPs with primary sedimentation, the choice can be different as customisation is necessary.

Abstract
In hospital water systems legionellae may be resistant to disinfectants in pipework, which is a problem particularly in areas where there is low flow or stagnation of water. We evaluated legionella colonization of a water network of an Italian hospital after time flow taps (TFTs) installation in proximity to dead legs. The water volume flushed was 64 L/day from May 2016, and 192 L/day from December 2016. Before TFTs installation, Legionella pneumophila sg2-14 was detected in all points (4 × 104 ± 3.1 × 104 cfu/L). All sites remained positive (2.9 × 104 ± 1.9 × 104 cfu/L) through November 2016. From December 2016 legionella persisted in one point only (2 × 102 to 6.8 × 103 cfu/L). TFTs with chemical disinfection may reduce legionella colonization associated with dead legs.

Abstract
BACKGROUND Patients receiving haemodialysis are exposed to a large volume of dialysis fluid. The Italian Society of Nephrology (ISN) has published guidelines and microbial quality standards on dialysis water (DW) and solutions to ensure patient safety. AIM To identify microbial and chemical hazards, and evaluate the quality of disinfection treatment in DW plants. METHODS In 2015 and 2016, water networks and DW plants (closed loop and online monitors) of nine dialysis wards of Italian hospitals, hosting 162 dialysis beds overall, were sampled on a monthly basis to determine the parameters provided by ISN guidelines. Chlorinated drinking water was desalinated by reverse osmosis and distributed to the closed loop which feeds all online monitors. Disinfection with peracetic acid was performed in all DW plants on a monthly basis. FINDINGS Over the 24-month study period, seven out of nine DW plants (78%) recorded negative results for all investigated parameters. Closed loop contamination with Burkholderia cepacia was detected in a DW plant from January 2015 to March 2015. Pseudomonas aeruginosa was isolated from March 2016 to May 2016 in the closed loop of another DW plant. These microbial contaminations were eradicated by shock disinfection with sodium hypochlorite and peracetic acid, followed by water flushing. CONCLUSION These results highlight the importance of chemical and physical methods of DW disinfection. The maintenance of control measures in water plants hosted in dialysis wards ensures a microbial risk reduction for all dialysis patients.

Abstract
IntroductionDue to the professional activities acute stress disorder and PTSD are most diffuse disorders among military servants. Number of studies revealed relationships between post-traumatic stress and depression, anxiety or somatic complaints.ObjectiveThough Georgian military personnel actively take part in the international peacekeeping missions since 2004 and no research was conducted to investigate the prevalence of abovementioned disorders.AimsThus, this study aims to investigate the prevalence of PTSD, depression, anxiety and somatic complaints in the cohort of Georgian military servants.MethodThe research participants were 2799 military servicemen who had been deployed on the 6 month long period to the peace-keeping missions and were screened for psychological problems after deployment. All of them were Caucasian males, with average age of 29.3 years. All participants were asked to complete a PTSD Checklist for DSM-5 (PCL-5), as well as a 15-item somatic subscale of the Patient History Questionnaire (PHQ-15), a 9-item depression subscale of the Patient History Questionnaire (PHQ-9), a 7-item anxiety subscale of the Patient History Questionnaire (GAD-7).ResultsPrevalence rate of probable PTSD screened by the PCL-5 was 2.7%. Further investigation showed that depressive, anxiety and somatic symptoms among them was 21.6%, 8.7% and 21.7% respectively.ConclusionAppreciable positive relationship was found (r = 0.65–0.70; P < 0.001) between these variables in the deployed military servants. Therefore, it is recommended that military servants should be screened on all above mentioned conditions along with PTSD, in order to see full picture of co-morbid problems.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Polyneuropathy has been reported in cerebrotendinous xanthomatosis (CTX), although its nature and possible association with certain genotypes and phenotypes are unclear. The effect of chronic administration of chenodeoxycholic acid (CDCA) on peripheral nerve conduction parameters is still debated. We report clinical, laboratory, and electrophysiological findings in 35 CTX patients. Twenty-six subjects (74.2 %) showed peripheral nerve abnormalities. Polyneuropathy was predominantly axonal (76.9 % of patients) and generally mild. No correlation was found between its presence and clinical or biochemical data. In polyneuropathic patients, CDCA treatment improved electrophysiological conduction parameters, irrespective of the duration of therapy. Improvement mainly concerned nerve conduction velocities, whereas most nerve amplitudes remained unchanged. This means that CDCA treatment did not influence the number of axons activated by maximum electrical stimulation but increased the conduction of the still-excitable fibers. Our findings may suggest that CDCA treatment promotes myelin synthesis in nerve fibers with residual unaffected axons. The effect of therapy may therefore depend largely on the extent of irreversible structural damage to axons.

Abstract
1 A fructose-enriched diet induces hypertension, metabolic alterations and insulin resistance in rats, resembling human metabolic syndrome. Previously, we found that prostanoid production was altered in fructose-fed rats. 2 This study analysed the effects of incubation with noradrenaline (NA) and angiotensin II (Ang II) on prostanoid release in mesenteric vascular beds from control and fructose-fed rats. Animals which received fructose solution (10% w/v) for 22 weeks showed higher systolic blood pressure and triglyceridaemia. 3 In controls, NA increased 6-keto-prostaglandin (PG) F(1)alpha (prostacyclin metabolite) and thromboxane (TX) production. Ang II increased only TX release. In fructose-fed animals, NA increased 6-keto-PG F(1)alpha and TX. PGF(2)alpha (vasoconstrictor) was also elevated. Ang II also increased PGF(2)alpha and PGE(2) levels. 4 In conclusion, in fructose rats Ang II in vitro stimulates a vasoconstrictor prostanoid not stimulated in controls. This could be related to the observed in vivo blood pressure increase. In fructose-fed animals, NA and Ang II also augment vasodilator prostanoids, suggesting a compensatory mechanism because of long-term hypertension.

Abstract
AIMS The three main aims of the study were the assessment of the genetic relationship between a deviating Erwinia amylovora strain isolated from Amelanchier sp. (Maloideae) grown in Canada and other strains from Maloideae and Rosoideae, the investigation of the variability of the PstI fragment of the pEA29 plasmid using restriction fragment length polymorphism (RFLP) analysis and the determination of the number of short-sequence DNA repeats (SSR) by DNA sequence analysis in representative strains. METHODS AND RESULTS Ninety-three strains obtained from 12 plant genera and different geographical locations were examined by repetitive-sequences PCR using Enterobacterial Repetitive Intergenic Consensus, BOX and Repetitive Extragenic Palindromic primer sets. Upon the unweighted pair group method with arithmetic mean analysis, a deviating strain from Amelanchier sp. was analysed using amplified ribosomal DNA restriction analysis (ARDRA) analysis and the sequencing of the 16S rDNA gene. This strain showed 99% similarity to other E. amylovora strains in the 16S gene and the same banding pattern with ARDRA. The RFLP analysis of pEA29 plasmid using MspI and Sau3A restriction enzymes showed a higher variability than that previously observed and no clear-cut grouping of the strains was possible. The number of SSR units reiterated two to 12 times. The strains obtained from pear orchards showing for the first time symptoms of fire blight had a low number of SSR units. CONCLUSIONS The strains from Maloideae exhibit a wider genetic variability than previously thought. The RFLP analysis of a fragment of the pEA29 plasmid would not seem a reliable method for typing E. amylovora strains. A low number of SSR units was observed with first epidemics of fire blight. SIGNIFICANCE AND IMPACT OF THE STUDY The current detection techniques are mainly based on the genetic similarities observed within the strains from the cultivated tree-fruit crops. For a more reliable detection of the fire blight pathogen also in wild and ornamentals Rosaceous plants the genetic features of deviating E. amylovora strains have to be studied in detail.

Abstract
In this study we investigated the levels of Epstein Barr virus (EBV) DNA by quantitative polymerase chain reaction (Q-PCR) in serum, whole blood and peripheral blood mononuclear cells (PBMC) from anti-EA IgG seropositive or anti-EA IgG seronegative EBV infected renal transplant recipients. We compared serological data with the viral load to monitor the risk of developing post-transplant lymphoproliferative disorders (PTLD). All patients were asymptomatic and none of them developed PTLD at the time of the study. EBV DNA quantitation for each patient varied in whole blood and PBMC samples probably due to different numbers of mononuclear cells present in samples from which DNA was extracted (whole blood vs. purified PBMC). In 92% of the serum samples EBV DNA was undetectable probably due to absence of free genomes since the number of DNA copies detected in samples from whole blood and PBMC does not reach very high levels. The correlation between the presence of EA-antibody, considered serological evidence of EBV reactivation, and the viral load showed that 60% of EA-positive patients had quantifiable EBV DNA, whereas in 40% of EA-positive patients EBV DNA was undetectable, showing serological reactivity but no viral replication. Of the remaining EA-negative patients, EBV DNA could be detected in 71% of them, whereas 29% did not show EBV DNA, indicating no EBV replication. In conclusion, our results confirm that the presence of serum IgG anti-EA antibody is not a reliable marker of active EBV infection whereas the evaluation of the viral load in blood samples is a useful diagnostic tool to monitor and to better understand the course of EBV infection in immunocompromised renal transplant patients at risk of developing PTLD.

Abstract
We investigated the role played by the parafascicular thalamostriatal pathway, one of the major excitatory inputs to the striatum, in the D-1 receptor induction of c-fos messenger RNA expression in the rat striatum. The full D-1 receptor agonist, SKF-82958 (0.05, 0.1, 0.5 and 1 mg/kg, s.c., 30 min), dose-dependently induced c-fos messenger RNA in naive rat striatum as determined by northern blot analysis. One day following electrolytic lesion of the parafascicular thalamostriatal nucleus, striatal c-fos signal by itself was not altered but the stimulated expression of c-fos was strongly decreased. Sections of sham-operated and acute-lesioned dorsal striata of vehicle- or SKF-82958-treated rats were processed for in situ hybridization histochemistry at the single-cell level with an RNA probe for c-fos. The basal expression of striatal c-fos was poorly detectable in sham and lesioned groups. Sections of dorsal striata from sham-operated rats treated with SKF-82958 showed two types of labeled neurons for c-fos: the lightly and the very densely labeled neurons which are few in number. Thalamic lesion strongly reduced SKF-82958 stimulated expression of c-fos RNA in both types of labeled cells. The frequency distribution of c-fos labeling per neuron in dorsal striata of lesioned rats treated with SKF-82958 was shifted to the left, and its median was lower than in the sham-operated striata treated with the D-1 receptor agonist. The results provide evidence that the excitatory projections from the parafascicular nucleus of the thalamus, thought to operate primarily through the N-methyl-D-aspartate receptors, exert a facilitatory control over D-1 receptor-induced c-fos gene expression specifically in the dorsal striatum.

Abstract
Given q as the global frequency of the alleles causing a disease, any allele with a frequency higher than q minus the cumulative frequency of the previously known disease-causing mutations (threshold) cannot be the cause of that disease. This principle was applied to the analysis of cystic fibrosis transmembrane conductance regulator (CFTR) mutations in order to decide whether they are the cause of cystic fibrosis. A total of 191 DNA samples from random individuals from Italy, France, and Spain were investigated by DGGE (denaturing gradient gel electrophoresis) analysis of all the coding and proximal non-coding regions of the gene. The mutations detected by DGGE were identified by sequencing. The sample size was sufficient to select essentially all mutations with a frequency of at least 0.01. A total of 46 mutations was detected, 20 of which were missense mutations. Four new mutations were identified: 1341+28 C/T, 2082 C/T, L1096R, and I11131V. Thirteen mutations (125 G/C, 875+40 A/G, TTGAn, IVS8-6 5T, IVS8-6 9T, 1525-61 A/G, M470V, 2694 T/G, 3061-65 C/A, 4002 A/G, 4521 G/A, IVS8 TG10, IVS8 TG12) were classified as non-CF-causing alleles on the basis of their frequency. The remaining mutations have a cumulative frequency far exceeding q; therefore, most of them cannot be CF-causing mutations. This is the first random survey capable of detecting all the polymorphisms of the coding sequence of a gene.

Abstract
Previous single exposure (priming) to a dopamine receptor agonist greatly enhances the contralateral turning behaviour elicited by dopamine D1 receptor agonists in unilaterally 6-hydroxydopamine lesioned rats. In the present study we have investigated the levels of glutamate decarboxylase 67 and glutamate decarboxylase 65 messenger RNA in the striatum of 6-hydroxydopamine-lesioned rats primed with L-3,4-dihydroxyphenylalanine (L-DOPA) and challenged with the D1 receptor agonist SKF 38393, three days thereafter. As previously reported, levels of glutamate decarboxylase 67 messenger RNA increased in the striatum denervated by the 6-hydroxydopamine lesion as compared with the intact one. Striatal glutamate decarboxylase 67 messenger RNA levels, measured three days after priming with L-DOPA (50 mg/kg), further increased in the lesioned striatum while were not modified in the intact one. Administration of SKF 38393 (3 mg/kg) elicited a more intense contralateral turning behaviour in primed than in drug-naive 6-hydroxydopamine-lesioned rats but did not induce any change in striatal glutamate decarboxylase 67 messenger RNA. In contrast, striatal levels of glutamate decarboxylase 65 messenger RNA were not modified by either 6-hydroxydopamine lesions or priming with L-DOPA. The results show that priming with L-DOPA induces long-lasting changes in GABAergic neurons of the 6-hydroxydopamine-lesioned striatum. These changes might play a role in the increased behavioural response of striatal D1 receptors induced by priming.

Abstract
In the context of a project aimed at the identification of zinc finger proteins involved in skeletal muscle histogenesis and differentiation, we isolated a murine gene, named ZT2. The 2.44kb partial cDNA clone corresponds to the 3' region of the gene, and contains a 0.54kb open reading frame encoding four C2H2-like zinc finger domains, organized in tandem. This cDNA hybridizes with multiple transcripts (2, 4.5 and 7kb), whose expression levels vary in different tissues and at different developmental stages in the same tissue. At least in skeletal muscle we observed differences in the polyadenylation state of the transcripts at different stages of development. Moreover, ZT2 expression is correlated with cell proliferation and transformation. Sequence analysis and genetic mapping indicate that ZT2 is the homologue of ZNF125, one of the linked zinc finger encoding genes localized on human Chr 11q23. In humans, a high frequency of tumor-associated translocations is found in this chromosome region. As expected, ZT2 maps to the corresponding region on chromosome 9 in the mouse.

Abstract
A highly spread polymorphism flanking the 3. Calpha1 human IG heavy chain gene was identified. This polymorphism allowed the detection of an internal duplication within the 3' flanking region of both Calpha1 and Calpha2. This region has a regulatory function with four enhancer structures also present at the 3' end of the human Calpha2 as well as in that of mouse and rat single Calpha genes. The 5682-bp sequence of clone lambdapl8 described here starts 3' of Calpha1 and presents three open reading frames; one of them contains part of the tandem repeats with the 20-bp consensus described previously that is expressed in a poly(A)+ RNA and found in three dbEST clones of the human tonsillar cDNA library. Here, we demonstrate that in the CLF1 B lymphoblastoid cell line, this transcript is associated with polysomes. We also discuss the possibility of the presence of a new regulatory gene that does not encode an immunoglobulin and maps in the human IG heavy chain gene cluster.

Abstract
We investigated whether the parafascicular thalamostriatal pathway, one of the major excitatory inputs to the striatum, regulates the expression in rat striatum of messenger RNA encoding two isoforms of glutamate decarboxylase (mol. wt 67,000: glutamate decarboxylase 67 and mol. wt 65,000: glutamate decarboxylase 65). Acute (one day) and chronic (14 days) electrolytic lesions of the parafascicular nucleus resulted in 58% and 23% decreases in glutamate decarboxylase 67 messenger RNA expression, respectively, as determined by northern blot analysis. Glutamate decarboxylase 65 messenger RNA was not modified by either lesion. Sections of sham- and acute-lesioned striata were processed for in situ hybridization histochemistry at the single cell level with an RNA probe for glutamate decarboxylase 67. Labelling of glutamate decarboxylase 67 messenger RNA was decreased in both types of cells known to be present in the striatum, i.e. the lightly and the very densely-labelled neurons. The frequency distribution of glutamate decarboxylase 67 labelling per neuron in the lesioned striata, in fact, was shifted to the left and its median was lower than in the sham-lesioned striata. In view of the excitatory nature of the thalamostriatal pathway, we examined the subtype of glutamate receptors modulating the glutamate decarboxylase 67 gene expression. The N-methyl-D-aspartate-type receptor antagonist, dizocilpine, at 0.1-0.5 mg/kg i.p., produced a marked and persistent reduction in striatal glutamate decarboxylase 67 messenger RNA. The non-N-methyl-D-aspartate receptor antagonist, 6,7-dinitroquinoxaline-2,3-dione (12 nmol/side, i.c.v.) had no such effect. The results provide evidence that excitatory thalamostriatal afferents selectively modulate the gene expression of glutamate decarboxylase 67, probably through the N-methyl-D-aspartate subtype of glutamate receptors.

Abstract
Electrical stimulation (ten pulses of 0.5 ms, 10 V applied over 10 s at 10 Hz, 140 microA) delivered bilaterally to the prefrontal cortex or the parafascicular thalamic nucleus of freely moving rats facilitated acetylcholine release in dorsal striata, assessed by trans-striatal microdialysis. The facilitatory effects were blocked by coperfusion with 5 microM tetrodotoxin, suggesting that the release was of neuronal origin. The response of the striatal cholinergic neurons to prefrontal cortical stimulation was short-lived and required a longer period of stimulation (20 min) that the response to thalamic stimulation (4 min) to reach maximal effect. The alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA)/kainate glutamatergic receptor antagonist 6,7-dinitroquinoxaline-2,3-dione [DNQX; 12 nmol per side, intracerebroventricularly (i.c.v.)] and the AMPA antagonist 6-nitro-7-sulphamoylbenzo(f)quinoxaline-2,3-dione (NBQX; 12 nmol per side, i.c.v. or 12.8 microM infused into the striatum), but not the NMDA-type receptor antagonist MK-801 (0.2 mg/kg, i.p.), abolished the facilitatory effect on striatal acetylcholine release evoked by stimulation of the prefrontal cortex. By contrast, DNQX or NBQX did not prevent the increase in striatal acetylcholine release evoked by parafascicular nucleus stimulation, but MK-801, in accordance with previous results, did so. MK-801 by itself lowered striatal acetylcholine output while DNQX and NBQX did not. The results provide in vivo evidence that the cerebral cortex facilitates cholinergic activity in the dorsal striatum apparently through the non-tonic activation of AMPA-type glutamatergic receptors while the parafascicular nucleus does this through tonic activation of NMDA receptors. Both glutamate receptor types are probably located in the striatum. The overall results suggest that the two pathways operate independently to regulate striatal cholinergic activity through distinct mechanisms.

Abstract
ZT3, isolated from a murine muscle cell cDNA library by a low-stringency hybridization, encodes a zinc finger domain containing factor with a transcript of 5.0 kb. A 3' 2.5 kb partial nucleotide sequence contains an ORF of 1.5 kb where 17 canonical C2H2 zinc finger domains organized in tandem were identified. It maps on mouse chromosome 11, close to two mutations which affect skeletal formation. ZT3 expression depends upon differentiation of myogenic cells in culture, since it is upregulated with myogenin and inhibited in scr-transfected C2C12 cells. ZT3 is not expressed in NIH3T3 or C3H10T1/2 fibroblasts, but is induced when fibroblasts are myogenically converted by transfection with the muscle regulatory genes (MRFs). Its expression is also upregulated in the rhabdomyosarcoma cell line RD induced to myogenic differentiation by TPA treatment. In postimplantation embryos, ZT3 is diffusely expressed but higher expression is detectable in the neural tube and encephalic vesicles, in the somites and, at a high level, in the limb buds as they form. During further development ZT3 is expressed in many tissues of neuroectodermal and mesodermal origin, but its expression decreases during fetal development and in the adult it is restricted to skeletal and cardiac muscle and to spleen. This pattern of expression suggests a possible role played by ZT3 in differentiating skeletal muscle. Its expression in other tissues is compatible with the suggestion that members of this class of DNA-binding factors play different roles during post-implantation development and in the adult life.

Abstract
For the first time we have characterized an unoccupied site of Epstein-Barr (EBV) virus integration in a lymphoblastoid cell line, RGN1. The site of integration is about 1.5 kb downstream from the gene encoding the heavy chain constant alpha 1, specifying immunoglobulin A (IgA). Sequence and Southern analysis allowed us to hypothesize that integration occurred via a double exchange involving the viral latent origin of DNA replication (oriP) and the human DNA. The region involved in the integration is transcribed into poly(A)+ RNA in all the tested lymphoid lines, but not in the RGN1 line. We suggest a mechanism of integration primed by interactions between oriP and cell ori and its potential role in the establishment and/or evolution of EBV-carrying lines.

Abstract
The expression and distribution of the mRNA coding for galanin precursor, preprogalanin (ppGAL), were analysed in several rat hypothalamic nuclei (periventricular, paraventricular, supraoptic, dorsomedial and arcuate nuclei and the lateral hypothalamic area) during development by an in situ hybridization technique and computer-assisted grain counting over individual cells. ppGAL mRNA (expressed as number of grains/100 microns2) was detectable from postnatal day (PD) 1 in all the nuclei considered, and the amount of transcript per cell was 6-11 times less than in the adult. ppGAL mRNA progressively increased from PD8 to 14 to 21. The level of ppGAL mRNA in all the nuclei at PD21 was about half that in adulthood, except in the dorsomedial nucleus, where the difference was no more than 20%. As an index of the activity of galanin-containing neurons, we measured the basal and K(+)-evoked in vitro release of galanin-like immunoreactivity from hypothalamic slices of PD14, 21 and 90 rats by radioimmunoassay. Basal release of galanin-like immunoreactivity remained at the same level from PD14 to PD90, but the response to KCl (50 mM) stimulation was lower at PD14 (approximately 90%) and PD21 (> 200%) than at PD90 (350%). Basal and K(+)-evoked release was sensitive to tetrodotoxin, indicating a neuronal origin. This study provides the first evidence that the increase in ppGAL mRNA during the ontogeny of hypothalamic nuclei is associated with an increase in galaninergic neuronal function.

Abstract
The effect of the serotonergic 5-HT4 receptor agonists BIMU 1 and BIMU 8 on in vivo acetylcholine (ACh) release in brain hemispheric regions of freely moving rats was investigated using the microdialysis technique. Both agonists, applied intracerebroventricularly, facilitated the release of ACh selectively in the frontal cortex and were ineffective in the striatum or dorsal hippocampus. The facilitatory effect of BIMU 1 in frontal cortex was prevented by the selective 5-HT4 receptor antagonists GR 125487 and GR 113808 which by themselves did not alter basal release. the results provide the first evidence that serotonin facilitates ACh release in frontal cortex through stimulation of 5-HT4 receptors which are not tonically activated. 5-HT4 receptor agonists might thus offer a novel means of boosting central cholinergic function to overcome the cholinergic deficit in memory disorders.

Abstract
The origin of beta-amyloid deposited in senile plaques in Alzheimer's disease (AD) is not known. We compared the expression of protein precursor of beta-amyloid (APP) in the cell types involved in plaque formation. The levels of APP mRNA were determined in primary rat neurons and glial cells in culture, human endothelial cells and in a murine brain-derived endothelial cell line. Northern blot analysis was performed using an APP cDNA probe to detect the general APP sequence and an oligonucleotide (40 mer) complementary to the sequence of the Kunitz protease inhibitor (APP-KPI). The APP mRNA transcripts were abundant in all three cell types. The highest level of APP, normalized to beta-actin mRNA content, was expressed in neurons, followed by glial cells, where the APP expression was similar (94%) while in endothelial cells was lower (53%). The proportion between APP-KPI mRNA and total APP mRNA was high in endothelial, intermediate in glial and low in neuronal cells. We compared the effects of exposure to interleukin-1 (IL-1), a cytokine involved in several biological processes and elevated in AD, on APP mRNA expression in neuronal, glial and endothelial cells. In human endothelial and in brain-derived murine endothelial cells we observed a similar increase (50%) of total APP mRNA or APP-KPI mRNA after treatment with human recombinant IL-1 beta. In neuronal cells, IL-1 (200 ng/ml) substantially increased APP mRNA (175%), detected with both probes. In glial cells, the expression of APP mRNA did not appear to be altered by IL-1 (50-400 ng/ml). The results suggest a role of IL-1 in the neuronal mechanisms related to beta-amyloid protein deposition in AD.

Abstract
The expression of galanin (GAL) mRNA was determined by in situ hybridization after frontal deafferentation and colchicine treatment in the rat hypothalamus. Frontal deafferentation significantly increased the signal in the paraventricular nucleus (PVN), the supraoptic nucleus (SON), and dorsomedial nucleus (DMN). Colchicine treatment induced a diffuse enhancement of GAL mRNA in hypothalamic nuclei. When the two treatments were combined there was an additivity of GAL mRNA expression in the previous hypothalamic nuclei and also in the arcuate nucleus (AN), where the single treatments did not modify the signal. These results suggest the regulation of GAL mRNA expression mediated by a multineuronal pathway, separate from the colchicine-induced GAL mRNA increase.

Abstract
Clinical data, X-ray, findings, and the endoscopic and cytologic diagnosis of 94 patients admitted to hospital for gastric ulcer have been reviewed. The purpose of the study was to establish the frequency of malignancy and the reliability and comparative merits of clinical factors, radiology, endoscopy and multiple biopsies in arriving at exact diagnosis. The results show that endoscopy is the most accurate in differentiating benign from malignant gastric ulcers.
